In the past few months, GZDoom has evolved in the definitely most advanced sourceports - not only in terms of technical possibilites but finally also when it comes to visuals. Only few mods have really used the new possibilities but one mod finally took it to the boundaries: Doom Slayer Chronicles. The author bifurcator says, it is "compatible with all known gameplay mods for Doom2 and takes advantage of the newest features of GZDoom, such as hardware shaders, full-screen post-processing, PBR textures (normals and specular maps, also often called "bump mapping"), high-resolution textures, and of course dynamic lighting." The screenshots already speak for themselves. Check the development thread at ZDoom for some animated footage and more information, as this is close to a release.
